How to include our own mfile into matlab library?

Question

I have created my own mfile and would like to add it permanently lie built in functions so that I dont have to specify path. Is there a way to do it?

Answer 1

You should store your .m file (either script or function) in a folder belonging to the MatLab search path.

To add your own folder to the MatLab search path you can use eiterh:

• the Set Path tool, available on the MatLab Home toolbar

• use the buil-in function path (from the Command Window or, for example, as part of a script)

E. g.

path(path,'c:\my_folder\my_sub_folder')

Hope this helps.

Answer 2

Write your file and save it and then add the containing folder to the MATLAB search path. You do not need to look for it every time.

addpath('c:/matlab/myfiles')

Note: your filename should not exist within MATLAB, otherwise your file would be the default one, when you call that command.

You can also do most of the work from command-line: First, create a folder,

mkdir('c:/matlab/myfiles')

Add it to the top of your search path,

addpath('c:/matlab/myfiles')

and then save the search path for future MATLAB sessions

savepath c:/matlab/myfiles/pathdef.m
